I had a great time staying at George's place! It's a cozy apartment, had everything I need. And the complex is beautiful — it has billiards, 3 pools, a coworking space, and even a sauna.
It's not in the middle of the city. But it might as well be. It's a 10 minute walk from the Sukhumvit line on BTS, which will take you pretty much everywhere important in Bangkok.
There's also tons of delicious street food nearby, you can get a meal for like $2 USD by walking like 5 minutes.
My one complaint was that things didn't always work... the internet went out a few times, the air conditioning had to be repaired... but I think these things are under control now. By the time I left everything was perfect.
Highly recommend staying here!
